Dryandra—continued. 
Proleacem. А genus of about fifty species of handsome 
greenhouse evergreen shrubs, allied to Banksia, from 
which genus it is readily distinguished by the involucre, 
by the flat, or nearly flat, receptacle, and by the fruit. 
All are confined to Western extra-tropical Australia. 
They are very rarely seen in cultivation, notwithstanding 
their great beauty. For culture, see Banksia. 
D. armata (armed)* Ј.-Леайз yellow, terminal, closely sur- 
rounded by floral leaves longer than the flowers; involucre 
broadly ovoid or almost globular, Zin. long; bracts at first 
villous, at length becoming glabrous; perianth above lin. long, 
more or less villous; limb narrow, obtuse. J. 2in. to 3in. long, 
deeply pinnatifid with lanceolate or triangular pungent-pointed 
lobes, very rigid, flat or undulate, reticulately veined, and some- 
times slightly tomentose beneath. Young branches tomentose. 
h, 2ft. to 4ft. 1805. Syn. D. favosa. (B. M. 3236.) 
P pechntiolta (Blechnum-leaved) A synonym of D. pteridi- 
olia. 
D. falcata (falcate). This closely resembles D. armata in foliage 
 &nd inflorescence, but may be distinguished from that species 
by the glabrous perianth limb. Y oung branches usually tomen- 
_ tose and hirsute, with spreading hairs. А. 4ft. to 5ft. SYN.

DRYAS (mythological ; from Dryades, or nymphs of 
the Oaks; the leaves bear some resemblance to those 
of the Oak). Овр. Rosacee. A genus containing a couple 
of species of elegant dwarf hardy shrubby plants, natives 
cold and Arctic regions of the Northern hemisphere, 
Flowers white or yellow, large. Leaves simple, petiolate, 
oblong, entire, crenate or sub-pinnatifid ; margins recurved, 
Shining above, downy beneath. They are of easy culture 
a moist peat soil  Propagated by cuttings, by divisions, 
- or from seed. }

curious of orchids, and, until it flowered at Kew in
